Robot vacuums can help keep floors clean without having to use a conventional vacuum each time. A selection of three models featured in Amazon promotions includes options from WAP and Xiaomi.

The WAP Robot W90 combines vacuuming, sweeping and mopping. It has a 250 ml reservoir, dual-voltage operation and an anti-fall system designed to prevent it from going over stairs or steps.

The WAP W400 also offers three cleaning functions, with a larger 300 ml reservoir. It can be controlled by voice through Alexa or Google Assistant, and has 30W of power and dual-voltage operation.

At the higher end of the selection, the Xiaomi S40C uses smart mapping to navigate rooms. The compact white model is an official version for the Brazilian market and is presented as an option for more precise, programmable cleaning.
